Well, I grant you that I was a complete rookie when I bought my Aztec and probably did a lot of things wrong. I've still only been at it for a few months and have a lot to learn but I have made progress. Quite a bit as far as I'm concerned. And I still don't like the Aztec.
I did get mine on sale after the holidays and only paid $50 for the kit. A 430 with three nozzles, couple of bottles and a gravity cup, adapter, hose and a can of propel. I've seen 430s that were only single action but the one I got can be used single or double. I always sprayed thinner through it when I was done, soaked the nozzle and cleaned out the front of the body. Never took the body apart. It has always spit and sputtered, leaked behind the nozzle at times, and never atomized paint well.
Yesterday I bought a Badger 360 Universal and when I brought it home and tried it out, it was like a new day had dawned. I could not believe the difference. All I did was adapt the hose to my compressor, mix some paint, and let it fly. The paint came out in such a fine mist and went on so smoothly I almost fell over.
Last nite I painted the chassis and suspension to a F&F Supra semi-gloss black and it looks great. Tonite I painted a Viper body metallic black and the paint went on slick as can be. I've seen some people say that paint can't be sprayed without orange peel, it's a fact of life. Well, I beg to differ.
With the Aztec, I could not spray metallics or pearls without the paint running from the edges. With the Badger, I didn't even have to think about it. The only thing I can attribute that to is atomization. The Badger achieves a much finer spray than I was ever able to get from the Aztec.
So there's my testimonial. I'm a switcher.
